Explain what is meant by the circle of fifths.


assistant
The circle of fifths is a musical diagram which maps out all the different key signatures and their respective relationships to one another, by arranging them in a circle with the key of C in the center. It is based on the fact that when going in a clockwise direction, each successive key is a fifth higher than the previous one. This enables musicians to quickly work out the relationships between the different key signatures, which can be helpful in composition and arranging music.
